ALBERT C. TINSLEY, OF FAY, TEXAS.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 749,7 59, dated January 19, 1904.

Application filed October 7, 1903.

To all whom t may concern:

Beit known that I, ALBERT C. TINsLEY, a citizen of the United States, residing at Fay, in the county of Leon and State of Texas, have invented a new and useful Ealing-Press, of which the following is a specification.

This invention relates to baling-presses, and is designed for use in baling and compressing cotton.

The invention has reference more particularly to that type of baling-presses in which the cotton is compressed between a fixed head and reciprocating platen or plunger operated by means of a pair of oppositely-arranged steam-cylinders having pistons arranged for reciprocation therein, said pistons being connected with the plunger or platen by means of toggle-levers.

The object of the invention is to improve the construction of baling-presses of the type specified by providing improved means for guiding the reciprocations of the plunger, by providing improved means for supporting the. ends of the pistons to which the toggle-levers are connected, by providing a rest-block for the platen when at the bottom of its downward stroke, and by improving the means for introducing the cotton into the press for compression therein.

With the objects above stated in view the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly set forth in the appended claims.

In the drawings, Figure 1 is a view in side elevation of the complete press. Fig. 2 is a view in transverse vertical section through the baling-chamber and the reciprocating platen. Fig. 3 is a detail view in plan of a portion of one of the plates mounted on the bed-timbers and of one of the brackets with a roller mounted therein for travel over the plate. Fig. 4 is a detail sectional view in a plane at right angles to the plane of Fig. 2;

Referring to the drawings, in which corresponding parts are designated by similar characters of reference, l l designate bed-timbers upon which the other portions ofthe press structure are mounted. 2 2 2 2 are uprights Serial No. 176,146. (No model.)

rising from the bed-timbers and affording support for the press-box, which is divided into an upper portion 3, which may be referred to as the baling-chamber, and a lower portion 4, which may be called the charging-chamber. At the top of the standards 2 there is secured, by the means of nuts 5, a head or top 6,forming a fixed pressure-plate, against which the cotton may be pressed. Beneath the head 6 is arranged baling-chamber 3, which consists of end walls 7, a fixed side wall 8, and a swinging side wall 9, which is pivotally supported at its lower margin, Aso that it may be turned outward to the position shown in dotted lines in Fig. 2. The baling-chalnbeiis separated from the charging-chamber by supporting-bars 10, upon which the walls of the baling-chamber are supported, and these bars are cut away at their forward ends to permit the bar 11 at the top of the swinging side wall 9 to be lowered into the position indicated by dotted lines in Fig. 2 in order to facilitate tulle removal from the press of the completed The charging-chamber, which is disposed beneath the baling-chamber, comprises end walls 12, slotted at thelower margin, as shown at 13, and projecting forward from the press to afford support for a shaft 14. The charging-chamber also comprises a rear side wall l5 and a pivoted front wall 16, which may be depressed to facilitate the introduction of cotton into the charging-chamber.

The shaft 14 supports a pair of levers 17, connected. at their outer ends by means of a bar 18'and having their inner endsconnected by links 19 with bearing-brackets 20, mounted upon the front side wall 16 of the chargingchamber. The levers 17 and the members associated therewith thus serve as means for operating the pivoted front wall of the balingchamber and means for holding it in the position shown in solid lines when the press is in operation.

i Mounted on the bed-timbers 1 beneath the charging-chamber and between the standards 2 is arranged a resting-block 22, having an oblong base portion 23 and a central upwardlyprojecting portion 24. At'either side of the rest-block there are fastened upon the bed- IOO timbers track-plates 25, each having on the upper surface thereof a pair of parallel ridges 26, which form a track over which travels a grooved roller 27, rotatably mounted in a bracket 28 at the end of a piston-rod 29, connected to a piston which reciprocates in a steam-cylinder 30, mounted upon the bed-timbers. Each of the brackets 28 supports at one end a pair of toggle-levers 31, pivotally connected at the other end with a platen or plunger 32, which reciprocates vertically within the charging and baling chambers of the press. The platen 32 is attached to the upper end by a guide rod 33, which extends downward through an opening in the rest-block 22, within which the guide-rod has a sliding movement. The upper surface of the platen 32 is transversely grooved, as shown at 34, in the usual manner, and the lateral edges of the platen are provided with notches 36, whose utility will hereinafter be explained.

In the operation of the press cotton will be introduced into the charging-chamber by lowering the pivoted front wall 16 and introducing the cotton through the opening formed thereby. The cotton so introduced will rest upon the upper surface of the platen 32, and when a suicient quantity of cotton has been introduced upward movement will beimparted to the platen by admitting steam into the cylinders through a steam-pipe 37, having branches 38 leading to the two cylinders. Two valves 39 and 40, which may be designated as inlet and exhaust valves, respectively, are provided in the pipe 37, and by closing valve 4:0 and opening valve 39 steam will be allowed to enter the cylinders, thus imparting movement to the pistons and causing the platen to be forced upward in the charging-chamber by the toggle-levers 31. The cotton will be carried upward by the platen into the balingchamber and compressed by it against the top 5 of the apparatus. Closing the valve 39 and opening the exhaust-valve 40 will then allow the platen 32 to descend until it rests upon the rest-block 22, and the descent of the cotton from the baling-chamber will be prevented by pivoted dogs 41, mounted in slits 4:2 in the side walls of the baling-chamber and shown in the present instance as being twelve in number. These dogs project into the balingchamber, and owing to the presence of the notches 36 in the sides of the platen 32 the dogs do not interfere with the upward movement of the platen, but are effective to prevent the descent of the pressed cotton.

One charge of cotton having been carried upward by the platen and sufliciently compressed, another charge will be introduced into the charging-chamber and the operation repeated. This procedure will be continued until a suiiicient quantity of cotton has been compressed in the baling-chamber to form a bale, and the bale so formed will then be secured by ties in the usual manner and removed from the press by lowering the pivoted front wall 7 of the baling-chamber.

From the foregoing description it will be seen that by suitably proportioning the parts of the press and making use of cylinders of suiiicient size any degree of pressure which is desired may be produced in the apparatus and the bale of cotton compressed to any desired thickness.

By means of the tracks on the plates 25 and the grooved rollers 27 the brackets 28 at the ends of the pistons will be guided in their movement and will be supported so that the rnotion of the press is not impeded by friction. The rest-block beneath the platen will afford a support for the plate when not in operation, holding the platen at the proper height, and will also serve to prevent the platen from descending so far that the ends of the piston will be forced against the outer ends of the cylinders in which they reciprocate, thus insuring immediate response of the pistons when steam is admitted into the cylinders.

Having thus described the construction and operation of my invention, what I claim asnew, and desire to secure by Letters Patent, is-

1. The combination in a baling-press of a bed, a rest-block supported on said bed, a platen arranged for vertical reciprocation above the rest-block and normally supported on the restblock, oppositely-arranged cylinders and pistons at the ends of the bed, toggle-levers connecting said pistons and platen, and a pressurechamber within which said platen reciprocates.

2. The combination in a baling-press, of a bed, a rest-block mounted on said bed and provided with a central aperture, a platen normally resting upon said rest-block, a guiderod rigidly connected with said platen and eX- tending through the aperture in the rest-block, oppositely-arranged cylinders and pistons on said bed, toggle-links connecting said pistons and platen, and a pressure-chamber within which said platen reciprocates.

3. The combination in a baling-press, of a bed, a rest-block mounted on said bed and having an upward projection, a platen normally supported upon said projection, a pressurechamber within which said platen reciprocates, track-plates arranged on opposite sides of said rest-block and presenting parallel ridges forming tracks, oppositely-arranged pistons and cylinders at the ends of said bed, brackets mounted at theV inner ends of said cylinders, rollers having grooves engaging the ridges on said track-plates, and toggle-levers pivotally connected with said brackets and said platen.

In testimony that I claim the foregoing as my own I have hereto afiXed my signature in the presence of two witnesses.

ALBERT C. TINSLEY.
